Probably not, I'm guessing, due to the different sized rod ends.
Although it probably could be made to fit, it's not needed in our application anyway. The design of the #2390 system, when properly adjusted, minimizes the roll more common to the "1-ton" setups. It more closely follows the original Ford factory geometry.

It's the vertical orientation of the draglink to tie-rod interface that lets The Cure do it's job, while the 45° angle of our system (you can just see it in the pic you linked to) does not require it.

Thanks Paul, been very happy with the WH system and was mostly curious. For $20 what the heck! Thought I'd try it.
